SHUTTLE FOR SEWING-MACHINES.

SPECIFICATION forming' part of Letters. Patent'No. 690,616, dated January 7, 1902.

Original application iiled September 15, 1897, Serial No. 651,748. Divided and this application iled October 25, 1901.

Serial No. 79,916.' (No model.) v

To all whom it may concern: A

Be it known that I, VERNON ROYLE, a citi zen of the United States, and a resident of Paterson, in the county of Passaic and State of New Jersey, have invented a new and useful Shuttle, of which the following is a specication.

My invention relates to shuttles, with the object in view of providing a shuttle which will admit of vau inspection of the cop of thread within it without opening the'shuttle and in which the tension device is located on the exterior of the end of the shuttle out of the way of the cop of cord or thread within the shuttle. Y

My present application is a division of my pending application, Serial No. 651,748, filed September 15, 1897, entitled Machine for lacing jacquard-cards.

In the accompanying drawings, Figure 1 is is a longitudinal section showin g the position of the cop therein. rear end of the shuttle, and Fig. lis a transverse section in the plane of the line A A of Fig. 1.

The body of the shuttle is denoted by a and is made skeleton in form, being provided on each of four sides with yan elongated opening b. The rear lining c, of some thin materialsuch, for example, as sheet-brass-is inserted within the shuttle to receive the cop of cord or thread, and the said lining is cut away opposite one or more of the openings b, (in the present instance opposite the opening on the outer side of the shuttle or that side opposite the side wall of the raceway,) and a lm d, of some suitable transparent or translucent material-such for instance, as celluloid--is placed in the opening and serves to admit of an examination of the condition of the cop within the shuttle whenever the operator glances in that direction and at the same time protects the cop from dust 'and foreign substances. By this meansl the operator can determine at a glance when the cop is nearly exhausted and so determine the time when a new cop should b e inserted before the end of Fig. 2

Fig. 3 is a view of the Athe previous cop is left too short to make a good connection.

The rear end of the shuttle a is provided with a cap e, which cap is in the present instance hinged to the body portion of the shuttle and retained in its closed position by a spring-catch f. (See Fig. 3.)

VThe outer face lof the cap e is preferably dished, as shown at g, (see Fig. 2,) and within this dished portion the tension-spring his loi cated. y The .cord c' from the cop within the shuttle is led from the crown of the cap e at the rear end ofthe shuttle and thence beneath the tension device and along to the guide j, as shown in Figs. 1, 2, and 3. This serves to draw the cord directly from the interior of the cop without causing it to bind across the Vend of the cop, and hence causes the cop to unwind naturally and without any liability of becoming snarled. It also serves to locate the tension device entirely out of the way of the bearing-surface of the movable parts and out of the way of the cop within the shuttle and admits of constructing the cop with smooth unobstructed exterior side walls and with a smooth and unobstructed interior.

What I claim isl 1. A shuttle provided with one or more peep-holes through its wall and a transparent film covering the said peep hole or holes, substantially as set forth.

2. A shuttle comprising a body portion and 'a cap at its end for closing and opening access to the interior of the shuttle, the said cap n being provided with a cord-discharge opening therethrough and with -a tension device located on the exterior of the cap, substan- Atially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 16th day of October, A. D. 1901. f
